Her husband, Prince William, shared Middleton's creative hobby with reporters after after presenting an Order of the British Empire, a distinguished accolade honoring exceptional individuals, to Johanna Basford, the best-selling illustrator of Kate's coloring book of choice, Secret Garden ($10; amazon.com).
